Re: Safe to Swim in High Chlorine levels

Thanks for the quick response!!! I have two eager little boys and I didn't want them to come out with bleached hair , they have green light to swim now!
I will monitor my FC with the FT100 test kit and hope to be done with the algae at once! I forgot to add that my CC was 0.

Re: Safe to Swim in High Chlorine levels

The 24 ppm with 40 ppm CYA at your pH is roughly equivalent to a pool with 1.5 ppm FC and no CYA so similar to many indoor pools. Nevertheless, the high FC level means you don't want to be drinking lots of pool water so if your kids are real gulpers/drinkers then consider keeping them out. Getting a little water sipped in is no problem -- I'm talking about serious drinking which I presume is unlikely. This exposure is also presumed to be short-term since at some point hopefully soon your shocking will be over.

The EPA limit of 4 ppm FC assumes drinking around 2 quarts of water every day so at 24 ppm this would be equivalent to 1-1/3 cups of your current pool water every day for months. CYA essentially doesn't absorb through the skin so it is unlikely that the chlorine bound to the CYA (which is 93% of the FC) does either.
